I'm not sure what's up with this. You might want to run
com.bbn.openmap.layer.shape.SpatialIndex -d -b <xxxxxxxx.ssx> to see
what the bounding boxes are for your shape file. The bounding boxes
should look like they are defined in decimal degrees.

This doesn't zoom in, it zooms out. Smaller values = larger scales
((1:value) = scale), smaller values = zooming in.
